Hi community,
I try to create a 3D model of a van (inside and outside). In the end I want to have a 3D model which I can use in CAD (and probably also print a small 3D model 
).
It’s my first photogrammetry project, and since I’ve strated I already noticed quite a few things which I should do differently the next time (e.g. taking higher quality pictures in better lighting) - still, any other tips are welcome as well!
I have an inside and an outside model which I want to combine.
I’ve used a Fairphone 5 for the inside and a DJI Mini 5 Pro for the outside.
Instead of images I’ve used a video each and imported them with a fairly small interval (0.5s for inside, 0.1s for outside), resulting in 1402 inside / 2825 outside images.
I know (now) that this is far from ideal, but for now I’m pretty happy with the outcome, although there are quite a few holes and bad spots which I will have to fix manually (and tips on improvemnents regarding that are also welcome).
Outside (Vertices/Solid/Sweet):
Inside (Vertices/Solid/Sweet):
But now to my issue/question:
I’ve used 6 control poinst (3 on each side) to combine the inside and outside model, and it appears to align quite nicely.
My issues is now that there are suddenly much more holes in e.g. the roof than with the individual models, and I’m wondering why.
It seems almost like where the two models slight overlap / touch that information is removed?
Combined (Vertices/Solid/Sweet):
Beside any other tips on how to optimize the model overall: how can I prevent this from happening when combining inside & outside?
Many thanks in advance!
